In the program Foreign Correspondent also spoke to Australian and Italian startup founders looking to make it in Silicon Valley. On being asked what they hoped their business was worth they all had the same answer – a billion dollars.

Every founder in the current app or web 2.0 craze says “it’s not about the money, it’s about changing the world” yet scratch them and they are all on the lookout for the greater fool buying them out for an improbable sum.

One could say that a billion dollar cheque does change the world of the person cashing the thing although exactly how a iPhone photo app changes the world may escape some of us.

If the billion dollar valuations are going out of the startup mentality then it might be better for all of us. It might mean our youngest, best and brightest really are focused more on building things that will change the world rather than buying mega-yachts for themselves and their VC investors.
